Biometric Surveillance

Biometric Surveillance is the state of the art surveillance system which enables to use his body part as a key. This type of surveillance is based on a technology that measures and also analyzes the physical parts of a human beings and even human Behavioural characteristics and authenticates the same. Physical characteristics may include fingerprints, the retina of the eye, iris, and handprint and so on. Behavioural patterns include facial expressions, signature, voice, style of walk etc. It is based on the assumption that such physical and Behavioural patterns cannot be replicated and therefore acts as a secured password.

A biometric system offers the following three functions: Verification, Identification and Screening.

Verification: This provides a check on the claim made by the person to be someone. It checks whether the claim made is correct or not. The persons biometric information can be stored in a card or checked through the data save in the database.

Identification: Biometric information can extract the information as to identify the person. The data stored can be matched to find out the identity of the person concerned.

Screening:  This process makes possible to check if there is unauthorized access. For example, biometric information can identify a criminal on the loose. This would paralyze the criminal to move about in the fear of being identified. This process enables prevention of access to restricted area.

Biometric surveillance is increasing in its popularity as it combats the problem of people carrying false identity cards. One of the oldest forms of biometrics is the use of fingerprints. No two persons, even if they are twins, can have the same fingerprint. In fact the same person cannot have two fingers with the same imprint. Thus, this unique pattern enables a person to have a unique identification key. This also helps police to identify suspects.
